The present invention refers to a safety road barrier. The Road Barrier comprises a steel mechanism, which comprises a base plate over which a guide frame is located, this frame being a rectangular rigid body having a rectangular guide in each inner lateral surface, a control booth including a plurality of plates forming a rectangular room, this booth being fastened to the front surface of the guide frame by means of screws, this booth may house the control and power elements. Bases are screwed to the base plate, each base comprising a chair in the upper portion thereof where the actuator means, a cylinder-piston arrangement or telescopic cylinders, are fastened by means of split flanges, once the same are fastened to the base, these would be fastened to an inner plate of the mobile barrier by means of chairs. The mobile barrier includes a plurality of welded plates forming a rectangular body with inner and fixed horizontal plates, the mobile barrier having two squared-shaped guides i n each lateral surface, a plurality of reinforcement bolts are arranged lengthwise the guides, which are welded by both surfaces. Another embodiment of the invention comprises a signaling light bar, this embodiment comprising said light bar protruding from the upper portion of the mobile barrier, this embodiment includes a chair arranged in the inner fixed upper plate over which the cylinder-piston arrangement is located, this arrangement is intended to release the signaling light bar placed in the end portion of the stem of said cylinder-piston arrangement; this embodiment requires holes in the upper plate of the mobile barrier for releasing the signaling light bar. In another embodiment, the invention includes an arrangement of telescopic cylinders for avoiding the transit over the road barrier, these telescopic cylinders being arranged and screwed lengthwise the inner fixed upper plate, this embodiment includes holes in the upper portion of the mobile barrier for releasing the mobi le components of the telescopic cylinders. In another embodiment, the lifting cylinder-piston arrangements may be replaced by telescopic cylinders for acquiring more height, in this embodiment the mobile barrier and the guide frame are increased according to the desired height. |
